invention relates in general "to. material; handling apparatus and inoreparticuflarlyto handling apparatus of .theftypeemfloodying a sled or bucket designed for the 5 transportation of earth or other excavated] ywhich will be hereinafter more fully de- In my copending 'application, filed October 11, 1929, Serial K013983237, there is disf glosed aneizcavatingisysteni especially de- 10 signed and adapted for use in constructing I levees. In the excavatingsystem of'said ap' plication crawler; wagons are utilized forv transporting the earth from the borrow pit z 'to the'leveelsite. Under many circumstances 15*.and conditions these crawler wagons are ventirely satisfactory but where the earth'that isexcavated and transported is wet and of a sticky, muddy or clay-like consistency naybe preferable to utilize a mud sled or 'Z-Q sled'bucket in lieu of crawler wagons for the purpose of transporting the earth from the borrow pit to the levee site. 7 The present invention proposes a novel construction of sled bucket and a novel organization of the sled bucket with oper ating' lines, that is,'witli the haul back and haul in lines of the excavatingsysteni of the application above referred to whereby the T bucket may-be speedily transported from the 7 so borrow pit at which it is loaded to the levee site and speedily dumped and returned to the borrow pit under the control and actu: ation of the haul back and haul in lines.

,One of the principal. objects of the present inventionresides,inthe feat-ureof utilizing the haul back and haulin lines for the dual purpose of transporting and dumping the bucket. The dumping of the bucket in ea speedy and efiective-mannerinvolves a i problem of special difliculty which will perhaps be best appreciatedwhen it is undertive in operation and easy andcomparativei'ly mexpensive to manufacture. Other objects and advantages reside in" certain novel features of the construction,

arrangement and combination of parts scribed and particularly pointed out in the Figure I is a diagrammatic view -illus-' tinting-the sled bucket and its organization 1 with the haul in and haul back lines Figure 2 is a view showing the sled bucket in 'top plan and also illustrating somewhat diagrammaticallythe connection of the sle bucket to its operating lines;

Figure 3 is a diagrammatic view inside elevation showing the connection of the operating lines to the bucket just prior to the dumping; and

Figure 4 is a view similar to Figure 3 but showing the action of the lines in over turningor dumping the bucket. Referring to-the drawings, and more particularly, to 'Figures land 2, the numeral 1 designates generally a mud sled or sled bucket which is constructed with a bottom 2, side walls 3 and a backwall 5 all -suitably connected together and, if desired, suitably reinforced. In the construction illustrated,

the marginal portions of the bottom walland backwall are shown asoverlapping the adjacent edges of the sidewalls. However, the details of the bucket structure may be: varied. The top of the bucket is open. As shown in Figure 1, each side wall'3 has its upper edge inclining downwardly towardthe frontend of the bucket and its lower edge inclining or sloping upwardly adjacent the front end of the bucket. The bottom'2 is also upwardly inclined at the front end of the bucket in a manner'corresponding to the upward inclination of the lower edges of the side walls3, as indicated at 2'."

It will be understood at this point that the sled bucketis used in lieu of the crawler wagon in, the excavating system of my 00- pen'ding application above referred to, and is loaded at'the borrow pit by meansof a suitable 'excavating' machine, such as a dragline, powershovel, or the like. i Forthe purpose of transporting the bucket from the borrow pit to the leveesite it is connected vup with the haul in line and haul back line-11- operated from the power; driven drums-12 andj 13. is'l he druinsare:
